I'm late to the game but wanted to provide some context for the discussion. The dominant EMR in hospitals is Epic - can't find a cite but the ballpark is that more than 80% of academic medical centers<i></i> have adopted (ie, paid through the nose for) Epic.<p>As a clinician, I find Epic to be horribly clunky - it definitely detracts from time with patients and impairs collaboration among clinicians by 'hiding' important details in multiple sections/submenus. It's like a Frankenstein's monster of Windows 3.1 and Atari 2600 Basic.<p>As a researcher, the very restrictive agreements that Epic insists upon have a profound impact on our ability to a) make good use of health records data for research and b) develop extensions to Epic, for things like decision support and risk stratification. (In the latter case, they essentially 'own' anything that touches their code.)<p>BUT - like the old saying goes, no one ever got fired for buying IBM.<p>Moral of the story: Hooray for OpenEMR, VistA, and all the open platforms! This round was lost to Epic, but hopefully the next round we can do better.<p>(edit: <i></i> - academic medical centers in the US. Rest of world, you can do better!)
